View address when entering derivation path

[laboon]

On Parity Signer, the final address was displayed as the user entered the derivation path. This allowed for easy checking that you have entered the correct derivation path. Now, however, one must wait until the derivation path is finished, then enter your PIN, then confirm that you have written it down, then scroll through all of the derivation paths already entered to make sure it is correct. This is a time-consuming process when one has many derivation paths.

Instead, the device should show the address on the same screen entering the derivation path.
